    摘要： A three-tandem (3T) perovskite/silicon (PVT)-based tandem solar cell (TSC) includes an antireflection coating (ARC), a first transparent conductive oxide layer (TCO), a hole transport layer (HTL), a perovskite (PVT) layer, a second transparent conductive oxide layer (TCO), an electron transport layer (ETL), a plurality of buried contacts, a p-type Si layer, a p-type wafer-based homo-junction silicon solar cell, a n+ silicon layer, a back contact layer. The solar cell further includes a top sub-cell, a bottom sub-cell and a middle contact-based tandem. The top sub-cell includes the PVT layer. The bottom sub-cell includes the silicon solar cell. The middle contact-based tandem includes the second TCO layer to be used as the middle contact-based tandem, as well as a recombination layer for current collection. Further, a conduction and a valence band edge are employed at a front surface of the ETL.

    摘要： A perovskite-silicon tandem cell capable of absorbing solar radiation with energy lower than that of 1.12 eV, i.e., the bandgap of crystalline silicon—corresponding to the wavelength of 1100 nm. Ho3+ can absorb photons of wavelength range 1120 to 1190 nm, Tm3+, 1190 to 1260 nm, and Er3+, 1145 to 1580 nm, but up-conversion can be achieved using Ho3+, Tm3+, and Er3+-doped metal oxide, such as ZrO2, in perovskite-silicon tandem solar cells. Doped metal oxides, such as ZrO2 can also work as selective contacts. Such perovskite-silicon tandem structures can achieve over 30% solar energy conversion efficiency.

    摘要： A layered dual hydroxide (LDH) composite is provided. The LDH composite includes a nickel (Ni)-cobalt (Co)-LDH, and a nitrogen (N) and sulfur (S) co-doped reduced graphene oxide (rGO-NS), where the Ni—Co-LDH is at least partially enfolded by the rGO-NS to form the LDH composite. An electrode including the LDH composite is also provided.
